ANTOINE DE B. LOVETT AND EMMETT S. GOFF, OF GENEVA, NEWT YORK.

SPECIFICATION forming part of Letters Patent No. 367,007l dated July 19, 1887.

Application filed November 17, 1886. Serial No. 219,150. (No model.)

To @ZZ whom it may concern.-

Be it known that we, ANTOINE DE B. Lov- ETT and EMMETT S. GOEE, both residents of Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Hay-Tedders; and we do hereby declare that the following is a full,clear, and exact description of theinvention, which willenable others skilled inthe art to which it appertains to make and use thc same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective rear view of our improved hay-tedder. Fig. 2 is a similar View from above the tedder. Fig. 3 is a longitudinal vertical sectional view. Fig. 4 is a perspective detail view of the clutch mechanism at one end of the machine. Fig. 5 is an enlarged detail View ofone of the tedder-forks and its connections, and Fig. 6 is a detailview showing the divided shafts 34 and the manner of trussingthe frame of the rake.

Similar numerals of reference indicate corrtsponding parts in all the figures.

Our invention has relation to that class of ha y-tedders in which the forks or tedders are operated by means of a crankshaft; and it consists in the improved construction and combination of parts of such a tedder, as hereinafter more fully described and claimed.

In the accompanying drawings, the numerals 1 and 4 represent the top and bottom bars of the tcdder-frame; 3, the end pieces; 12, a central brace or support, and 3l an ordinary truss-rod,seeured at its endsto the under side of thetop bar. A pair of shafts, 1S, is secured to the top bar by means of bolts at their rear ends,and also by suitable side braces. Acrosspiece, 17, is secured to the shafts and also to the outer end ofa bar, 20, the rear end of which is secured to the top bar,1. Each of the end pieces, 3,is provided with two stubs or joui'- nals, on one of which, 5, the driving-Wheels 6 are secured, and on the other the cog-wheels S. An interior gear-wheel, 7, is secured to each of the drivevwheels in such a manner that they will mesh with the wheels S,and through them communicate motion to the pinions 9 upon the ends of the crankshaft 1l, for operating the tedders. This shaft is provided with a number of double cranks and can be made of one piece and be operated by only one set of gear-wheels at one end; butwe prefer to make it in two sections, the interior ends of which arejournaled in bearings in the braee-piece 12 and the outer ends in the endV pieces, 3 3. The outer ends of these shafts are made polygonal,as shown at or they maybe provided with the ordinary iin, by means of which the pinions 9 are secured to them to cause their rotation. Secured at their forward ends to the cranks 21 of the crank-shaft by means of ordinary strap-loop 26 are the tcdderarms 22. The rear ends of these arms,to which the forks 27 are seeured,are suspended by means ofthe links 33 from springs 31,which are secured at one end to the top bar of the frame. These links can be hinged directly to the arms, and springs or loops, as shown,may be interposed, and the forks 27 may also be provided with a coil, 28, and be secured to the arms by means of eyebolts or staples 30, orin any other wellknown manner. Each of these arms can also be made of wood and provided upon its under side with a flat strap, 24, formed into eyes at the rear end and into a hooked strap or loop, 26, at its forward end,although we do not limit ourselves to any particular construction of any of these parts or the frame. As the tedderforks are drawn forward the springs 3l will yield sufficiently to permit the fork to pass over thehayor any obstruction, but after they have caught in the hay and started baekward the springs are kept from bending downward too far by means of the supporting-bar 2,which is rigidly secured to and parallel with the top bar,1, by means of the short end pieces, 13. By means of this construction we attach the ends of the arms to the crankshaft, thus securing a direct application of power,whieh will also permit of free lateral motion of the outer ends of the arms as the fork ispassing Aan obstruction; anchas each arm is suspended from a separate spring, each fork can move independently of all the other forks and the point of support of the arm has but `little vertical motion.

XVhen it is desired to throw either or both sections of the crank-shaft out of operation,the driver places his feet upon the chains 19 and pushes them down. The inner end of each of IOO these chains is attached to the bar 2O and its outer end to the rcar endlof the springbar 16, which is secured at its forward end to the outer end of the cross-piece17 and at its forked or slotted rear end 15 to thepinion 9, the pinion being provided with a grooved collar, 14,

with which the forked end of thespring 16 engages. This causes the pinion to be drawn inward upon the end of the crank-shaft and out of engagement with the cog-wheel 8. As soon as the chains are released, the springs force the pinions 9 back into engagement and put the crank-shaft again'in operation. In`this manner a small obstruction can be passed without stopping the shaft its entire length. When it is desired to pass from one field to another, the chains can be drawn in andsecured upon a hook, 35, thus holding the pin-v ions at each end out of engagement.

Having thus described our invention, we claim and desire to secure by Letters Patent of the UnitedStates- 1. In a haytedder, the combination of a frame,a fork-operating shaftj ournaled therein, a ymovable pinion upon each end of said shaft,

springs secured at their front ends to said frame and engaging by their rear ends with and holding said pinions in or out of engagement with the operating mechanism, and chains secured to the said s'prings'and frame.

2. In a hay-tedder, the combination of a frame,aforkfoperatingshaftjournaled therein,

abar, 20, the rear end of'which is secured to the top bar of the frame, ahook upon said bar 20, springs secured at their front ends to the sides of said frame and holding the operating mechanism in or ont ofengagement with their rear ends, and chains secured to said first-inentioned bar and to said springs, the interxnedi ate portions of said chains being adapted to vbe secured upon said hook.
